Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the application. Rather, they are merely examples of apparatus and methods consistent with aspects of the application as detailed in the accompanying claims.

First, a network device according to the communication system of the present application will be described.

The radio access network device in the embodiment of the present application may be an evolved NodeB (eNB or eNodeB) of an LTE system, or may be a base station of a global interoperability for microwave access (worldwide interoperability for microwave access, wiMAX) communication system, a next generation base station (the next Generation Node B, gNB) in a fifth generation (5th generation,5G) communication system or a New Radio (NR) system, a future communication system (e.g., a sixth generation mobile communication system), or the like, which is not limited by the embodiment of the present application.

The terminal device in the embodiments of the present application may refer to a User Equipment (UE), an access terminal device, a subscriber unit, a subscriber station, a mobile station, a remote terminal device, a mobile device, a User terminal device, a wireless communication device, a User agent, or a User Equipment. The terminal device may also be a cellular telephone, a cordless telephone, a session initiation protocol (session initiation protocol, SIP) phone, a wireless local loop (wireless local loop, WLL) station, a personal digital assistant (personal DIGITAL ASSISTANT, PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a future 5G network or a terminal device in a future evolved satellite communication system (public land mobile network, PLMN), etc., as embodiments of the present application are not limited in this respect.

The subsequent embodiments of the present application will be described by taking a first radio access network device (gNB 1), a second radio access network device (gNB 2), a first terminal device (UE 1), a second terminal device (UE 2), a third terminal device (UE 3), a fourth terminal device (UE 4), a fifth terminal device (UE 5), and a sixth terminal device (UE 6) as examples.

The first terminal device, the second terminal device, the third terminal device and the fourth terminal device are connected to the communication system in a wireless manner through the first radio access network device.

The Dynamic/Flexible TDD (Dynamic/Flexible time division duplex; TDD: time Division Duplexing, time division duplex) scene and the subband full duplex scene according to the present application will be described in detail.

Scene 1: dynamic/Flexible TDD scenario.

Fig. 1 is a schematic diagram of a possible Dynamic/Flexible TDD scenario, where a first radio access network device and a second radio access network device are radio access network devices with similar geographical locations.

The slot of the cell of each radio access network device in the Dynamic/Flexible TDD scenario may be shown in fig. 1, where the first radio access network device and the second radio access network device communicate with terminal devices in respective coverage areas on transmission resources in the same frequency domain. For example, in the scenario shown in fig. 1, the TDD slot configuration of the cell of the first radio access network device is as shown in the gNB1 slot in fig. 1: downlink transmission is performed on slot1, and uplink transmission is performed on slot2-slot 5.

TDD slot configuration of the cell of the second radio access network device, as indicated by the gNB2 slot in fig. 1: downlink transmission is performed on slot1-slot4, and uplink transmission is performed on slot 5.

Taking this example as an example, on slot 2, the first radio access network device is uplink transmission, the second radio access network device is downlink transmission, and since the transmission power of the radio access network device is larger and the transmission directions of the first radio access network device and the second radio access network device are opposite, on the transmission resources of the same time-frequency domain, downlink transmission between the fifth terminal device and the second radio access network device, and/or downlink transmission between the sixth terminal device and the second radio access network device may generate interference for uplink transmission between the first radio access network device and the first terminal device and/or the second terminal device and/or the third terminal device and/or the fourth terminal device, and the interference is CLI (Cross LINK INTERFERENCE ). In this example, the first radio access network device is an interfered (Victim) radio access network device and the second radio access network device is an interfering (Agressor) radio access network device.

Scene 2: sub-band full duplex scenario.

The sub-band full duplex refers to dividing frequency domain resources into different sub-bands at the radio access network equipment side, and simultaneously carrying out downlink transmission and uplink reception on the different sub-bands respectively. Fig. 2A-2D are diagrams of several possible sub-band full duplex time-frequency positions in the prior art. As shown in fig. 2A-2D, the frequency domain corresponding to the base station is divided into a plurality of sub-bands, and the sub-bands may include: an uplink sub-band, a downlink sub-band, and a guard band.

The coordinate system shown in fig. 2A to 2D has a vertical axis of a frequency domain (f) and a horizontal axis of a time domain (t). The Uplink sub-band is used for Uplink transmission, namely, a time-frequency region marked by Uplink (U) in fig. 2A-2D; the Downlink sub-band is used for Downlink transmission, that is, a time-frequency region identified by Downlink (D) in fig. 2A-2D; the guard band is an unoccupied frequency band set aside between the subbands, i.e., the time-frequency region between the uplink and downlink subbands in fig. 2A-2D. The guard band is used for isolating uplink and downlink sub-bands and preventing mutual interference caused during data transmission.

Under the full duplex of the sub-bands, the frequency domain resources can be divided into an uplink sub-band, a downlink sub-band and a protection band according to actual requirements. For example, as shown in fig. 2B, only one uplink subband is divided on the frequency domain resource, and one downlink subband is divided; as shown in fig. 2A, for one sub-band, the sub-band may be divided into uplink resources and downlink resources according to a time domain, so as to implement sub-band division as shown in fig. 2C and fig. 2D. It should be appreciated that how to divide the uplink sub-band, the downlink sub-band, and the guard band can be determined according to actual requirements, which is not limited by the present application. Through the above division mode, the sub-band full duplex technology is realized.

In the following, a detailed description of the possible presence of CLI between radio access network devices in a sub-band full duplex scenario is given.

The first wireless access network device and the second wireless access network device are wireless access network devices with similar geographic positions.

Fig. 3 is a schematic diagram of one possible sub-band full duplex scenario. As shown in fig. 3, in the case that the first radio access network device and the second radio access network device perform downlink transmission on slot 1, and perform full duplex on the sub-band on slot 2-slot 4, uplink transmission and downlink transmission can be performed simultaneously, and uplink transmission is performed on slot 5.

Taking this example as an example, on slot 2, since the situation is currently in the full duplex sub-band, that is, the first radio access network device and the second radio access network device are both in the scenario of downlink transmission and uplink reception at the same time in the slot. At this time, the first terminal device, the second terminal device and the fourth terminal device perform uplink transmission to the first radio access network device, and downlink transmission is performed between the third terminal device and the first radio access network device; and downlink transmission is performed between the fifth terminal equipment and the second wireless access network equipment, and uplink transmission is performed by the sixth terminal equipment to the second wireless access network equipment. In this scenario, the current downlink transmission of the second radio access network device may cause CLI between radio access network devices for the current uplink reception of the first radio access network device, and correspondingly, the current downlink transmission of the first radio access network device may also cause CLI between radio access network devices for the current uplink reception of the second radio access network device.

Based on the above-described scenario, in order to eliminate CLI existing between radio access network devices, CLI measurement between radio access network devices is required. However, how to measure CLI between radio access network devices is a problem to be solved.

In view of this, the present application provides a communication method, in which CLI measurement resources can be interacted between radio access network devices, and CLI measurement between radio access network devices is performed based on the interacted CLI measurement resources.

The following describes the technical scheme of the present application and how the technical scheme of the present application solves the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

In the scenario shown in fig. 1 and 3, a detailed description is given of a communication method provided in an embodiment of the present application. Fig. 4 is a flow chart of a communication method according to an embodiment of the present application. As shown in fig. 4, the communication method may include:

s401, the first radio access network device and the second radio access network device interact CLI measurement resource configuration.

The CLI measurement resource configuration may include at least one of: subcarrier size, cyclic prefix format, CLI measures the resource index of the resource, the CLI measures the time domain position of the resource, and the CLI measures the frequency domain position of the resource. The subcarrier size is used for indicating the size of the subcarrier where the CLI measurement resource is located; the cyclic prefix format is used for indicating the format of time domain symbols in the CLI measurement resources; the frequency domain location of the CLI-measurement resource may be indicated by a resource indication value (Resource Indication Value, RIV); the time domain position of the CLI-measurement resource may be indicated by a period of CLI-measurement between radio access network devices, and a slot position indication of a start of CLI-measurement per measurement period may be indicated by a length indicator (SLIV), for example, a number of start symbols and consecutive symbols within the time domain position.

Optionally, CLI measurement resources may also be associated with other signals to be indirectly indicated by the identity of the other signals. For example, the CLI-measurement resources are associated with a channel state Information reference signal (CHANNEL STATE Information-REFERENCE SIGNAL, CSI-RS), and thus the CLI-measurement resources used may be indirectly indicated in the CLI-measurement resource configuration by carrying an identification of the CSI-RS. The identification of the CSI-RS here may be, for example, an index of the CSI-RS. Or the CLI-measurement resources are associated with Synchronization signals and PBCH blocks (SSBs), so the CLI-measurement resources used may be indicated indirectly by carrying an identifier of the SSB in the CLI-measurement resource configuration. The identification of the SSB as referred to herein may be, for example, an index of the SSB. Or the CLI measurement resources are associated with an uplink Demodulation reference signal (Demodulation REFERENCE SIGNAL, DMRS), so the CLI measurement resources used can be indirectly indicated by carrying the identity of the DMRS in the CLI measurement resource configuration. The DMRS identification here may be, for example, an index of the CSI-RS.

The first radio access network device and the second radio access network device may interact with the CLI-measurement resource configuration through an interface for communication between the radio access network devices, which may be an Xn interface, for example.

For example, the second radio access network device may send the CLI-measurement resource configuration to the first radio access network device; or the first radio access network device may send the CLI-measurement resource configuration to the second radio access network device; or the first radio access network device may send a CLI measurement request to the second radio access network device, and the second radio access network device returns the CLI measurement resource configuration to the first radio access network device based on the request; or the second radio access network device may send a CLI-measurement request to the first radio access network device, and the first radio access network device returns the CLI-measurement resource configuration to the second radio access network device based on the request, and so on.

It should be appreciated that the above is given by way of example only, as some of the ways in which CLI measurement resource configurations may be interacted between the first radio access network device and the second radio access network device. Of course, other interaction flows may be adopted between the first radio access network device and the second radio access network device to implement CLI measurement resource configuration, which is not limited by the present application.

The CLI-measurement resource configuration interacted by the radio access network device over the Xn interface may comprise at least one of: subcarrier spacing, cyclic prefix format, resource identification of CLI measurement resources, frequency domain location, time domain location.

Wherein, the CLI measurement resource allocation indicates the subcarrier interval of the CLI measurement resource and the cyclic prefix through two configurations of subcarrier interval and cyclic prefix format; the CLI measurement resource is indicated by the resource identification of the CLI measurement resource, and the time-frequency position of the CLI measurement resource is indicated by the frequency domain position allocation and the time domain position allocation. Alternatively, the frequency domain location allocation may be indicated by RIV, the time domain location allocation may be determined by CLI measuring the period of the resource at the time domain location, an offset at the time domain location, or SLIV. Alternatively, the indication may be performed by the above-mentioned CSI-RS, DMRS, SSB or the like.

S402, the first radio access network equipment measures the CLI between the first radio access network equipment and the second radio access network equipment according to the CLI measurement resource configuration.

Correspondingly, the second radio access network equipment performs CLI measurement with the first radio access network equipment according to the CLI measurement resource allocation, so that the first radio access network equipment obtains the CLI between the first radio access network equipment and the second radio access network equipment.

In an exemplary embodiment, the second radio access network device sends out an interference signal on the corresponding CLI measurement resource according to the CLI measurement resource configuration, and the first radio access network device sends out a receiving signal on the corresponding CLI measurement resource according to the CLI measurement resource configuration to receive the interference signal, so as to perform CLI measurement.

Note that CLI-measurement resources related to this embodiment may be used for a first radio access network device to measure CLI between the first radio access network device and a second radio access network device. That is, the second radio access network device transmits an interference signal, and the first radio access device performs CLI measurement based on the interference signal. Optionally, the CLI-measurement resource may also be further used for the second radio access network device to measure CLI between the first radio access network device and the second radio access network device. That is, the first radio access network device transmits an interference signal, and the second radio access device performs CLI measurement based on the interference signal.

Alternatively, the second radio access device may perform CLI measurement after the first radio access device completes CLI measurement, or the first radio access device may perform CLI measurement after the second radio access device completes CLI measurement. Or the CLI measurement resources for the CLI measurement by the second wireless access device are interacted between the second wireless access device and the first wireless access device by adopting a separate process, and the interacted CLI measurement resources in the current process are only used for the CLI measurement by the first wireless access device.

The communication method provided by the embodiment of the application can be used for carrying out CLI measurement between the wireless access network devices according to the interactive CLI measurement resources between the wireless access network devices and carrying out CLI measurement between the wireless access network devices according to the CLI measurement resources, thereby solving the problem of how to measure cross-link interference between the wireless access network devices and the wireless access network devices.

With continued reference to the communication scenario as in fig. 3, in this scenario, the first radio access network device performs CLI measurement by receiving the interference signal sent by the second radio access network device on CLI measurement resources while measuring CLI between the radio access network devices. When there is a terminal device (e.g., UE1 in fig. 3) that is performing uplink transmission in the cell coverage of the first radio access network device, the interference signal sent by the second radio access network device and the uplink signal sent by the terminal device UE1 are received when the first radio access network device performs CLI measurement. Therefore, CLI measured by the first radio access network device between the radio access network devices may be affected by the uplink signal of the terminal device UE1, resulting in lower accuracy of the measured CLI.

Therefore, on the basis of the above embodiment, the embodiment of the present application may further reduce the effect of the terminal device for uplink transmission in the cell range covered by the first radio access network device on CLI measurement between radio access network devices in the following manners:

implementation a: and punching the uplink transmission of the uplink transmission terminal equipment.

Fig. 5 is a flow chart of another communication method according to an embodiment of the present application. As shown in fig. 5, the method may include:

s501, the first radio access network equipment sends first indication information to first terminal equipment in the cell coverage area of the first radio access network equipment according to CLI measurement resource allocation.

Correspondingly, the first terminal equipment receives the first indication information. The first terminal equipment is terminal equipment of first target resources with overlapped uplink transmission resources and CLI measurement resources in the cell coverage of the first radio access network equipment.

The first indication information is used for indicating the first terminal equipment to perform uplink transmission punching on the first target resource; the first target resource includes: and the uplink transmission resource of the first terminal equipment and the CLI measurement resource overlap.

The first target resource may be one that includes only: the uplink transmission resource overlaps with the CLI measurement resource, or the first target resource may include: the uplink transmission resource of the first terminal device, or the first target resource may include: CLI measures resources.

Because the first target resource at least includes the resource where the uplink transmission resource and the CLI measurement resource overlap, if the first terminal device performs uplink transmission on the overlapping resource, interference will be caused to the CLI measurement.

Therefore, by means of the embodiment, the first terminal device may be instructed to perform uplink transmission punching on the first target resource, so that the first terminal device does not perform uplink transmission on the first target resource, thereby eliminating the influence of uplink transmission of the first terminal device on CLI measurement performed by the first radio access network device on CLI measurement resources, and improving the accuracy of CLI measurement performed by the first radio access network device between the first radio access network device and the second radio access network device.

The first indication information may indicate, by indicating a location of a first target resource, that the first terminal device performs uplink transmission puncturing on the first target resource. The indication manner of the position of the first target resource may be determined based on the division unit of the resource, specifically, the division unit adopted by the communication system. For example, the Resource may be divided in units of Resource Blocks (RBs), or in units of Resource Elements (REs), or the like.

Hereinafter, uplink transmission puncturing is described in detail with respect to resources based on the RB level in the first target resource and resources based on the RE level in the first target resource, respectively.

Implementation A1: and (5) punching uplink transmission based on a Resource Block (RB) level.

In a possible implementation manner, the first indication information includes first frequency domain resource sub-indication information and first time domain resource sub-indication information, where the first frequency domain resource sub-indication information is used to indicate at least one RB included in a frequency domain by the first target resource, and the first time domain resource sub-indication information is used to indicate at least one time domain symbol included in a time domain by the first target resource, where the time domain symbol may be, for example, an orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbol, and so on.

The first indication information may be carried in downlink control information (Downlink control information, DCI) and sent to the terminal device. For example, the DCI may be DCI 2_4, the first frequency domain resource sub-indication information may be frequencyRegionforCI in timeFrequencyRegion in DCI 2_4, and the first time domain resource sub-indication information may be timeDurationforCI in timeFrequencyRegion in DCI 2_4, for example.

This implementation can be used for the aforementioned Dynamic/Flexible TDD scenario, or sub-band full duplex scenario.

It should be noted that, when the method is applied in a subband full duplex scenario, the time domain symbol indicated by the first time domain resource sub-indication information may also include a subband full duplex symbol. The subband full duplex symbol may be an indication that there is both a time domain symbol coordinated for uplink transmission and a time domain symbol configured for downlink transmission on the slot, as shown for example in slot2-slot4 of fig. 3. The punching is performed on the uplink transmission resource according to the first target resource, so that the first terminal equipment does not perform uplink transmission to the first radio access network equipment at the first target resource provider, thereby eliminating the influence on CLI measurement of the first radio access network equipment. Therefore, at least one time domain symbol included in the time domain by the first target resource comprises a sub-band full duplex symbol and/or an uplink symbol, so as to completely shield all uplink transmission resources affecting the CLI measurement.

In a subband full duplex scenario, in another possible implementation, CLI measurement resources have a mapping relationship with uplink subbands and/or guard bands. The mapping relationship may refer to an uplink sub-band and/or guard band used by CLI measurement resources.

Thus, in this implementation, the first indication information may include: and the identification of the uplink sub-band and/or the protection band corresponding to the first target resource is used for indicating the first target resource through the identification of the uplink sub-band and/or the protection band.

When the CLI measurement resource is configured on an uplink sub-band, the first indication information includes an identifier of the uplink sub-band corresponding to the first target resource, where the uplink sub-band and the uplink sub-band configured with the CLI measurement resource are the same sub-band; when the CLI measurement resource is configured on the guard band, the first indication information includes an uplink sub-band corresponding to the first target resource and/or an identification of the guard band, the guard band and the guard band configured with the CLI measurement resource are the same guard band, and the uplink sub-band is an uplink sub-band adjacent to the guard band. If the first indication information only indicates the uplink sub-band corresponding to the first target resource, the first terminal equipment only punches the uplink sub-band; if the first indication information indicates an uplink sub-band and/or a guard band corresponding to the first target resource, the first terminal equipment punches the uplink sub-band and the guard band adjacent to the uplink sub-band.

In this implementation manner, a mapping relationship between CLI measurement resources and an uplink sub-band and/or a guard band is preset in the first terminal device. The mapping relation may be predefined in a protocol, or the first radio access network device may adopt a dynamic or semi-static indication to the first terminal device in advance.

According to the implementation mode, the punching of the uplink sub-band and/or the protection band can be realized only by indicating the identification of the uplink sub-band and/or the protection band in the first indication information, and the first frequency domain resource sub-indication information and the first time domain resource sub-indication information are not required to be carried, so that the signaling overhead of the first indication information is reduced.

According to the method of the implementation mode A1 provided by the embodiment of the application, the part, overlapped with the CLI measurement resource, of the uplink transmission resource of the first terminal equipment is punched for the RB level, so that the first terminal equipment does not carry out uplink transmission to the first wireless access network equipment at the punching position of the uplink transmission resource, the influence of the uplink transmission of the first terminal equipment on the CLI measurement of the first wireless access network equipment is eliminated, and the accuracy of the CLI measurement between the first wireless access network equipment and the second wireless access network equipment by the first wireless access network equipment is improved.

Implementation A2: and (5) punching uplink transmission based on a Resource Element (RE) level.

The time-frequency position of the uplink transmission punching is associated with information carried in the first indication information. How to instruct the first terminal device to punch the uplink transmission according to the association is explained in three implementations below.

Implementation A2-1: the uplink transmission puncturing is indicated according to a CLI reference signal (REFERENCE SIGNAL, RS) (i.e., CLI RS). This implementation may be applicable to both Dynamic/Flexible TDD scenarios as shown in fig. 1, as well as sub-band full duplex scenarios as shown in fig. 3.

In this implementation manner, the cli_rs has a mapping relationship with a preset position of uplink transmission puncturing based on the RE level, and the first terminal may determine, according to the association relationship between the cli_rs and the position of uplink transmission puncturing, a first target resource that needs to be subjected to uplink transmission puncturing.

The first terminal device may store at least one identifier of cli_rs, and the first indication information may indicate the identifier of the first terminal device cli_rs, where the first terminal device determines, according to the identifier of the cli_rs, a location of puncturing on the corresponding uplink transmission resource. The position of the uplink transmission punching indicated by the target cli_rs overlaps with CLI measurement resources.

The first indication information may be dynamically sent by the first radio access network device to the first terminal device, that is, the first radio access network device determines and sends the first indication information to the first terminal device according to the CLI measurement resource configuration when the CLI is measured each time; the first indication information may also be a CLI measurement behavior of the same CLI measurement resource for a plurality of times in a period of time, and instruct the first terminal device to perform uplink transmission puncturing on the first target resource; the first radio access network device can also indicate the first terminal device statically, that is, the CLI measurement resource configuration of the first radio access network device and the second radio access network device is unchanged, the uplink transmission punching position indicated by the first indication information is also unchanged, and the first radio access network device can indicate the first terminal device to punch uplink transmission according to the CLI measurement period only by sending the first indication information to the first terminal device once.

Implementation A2-2: and indicating uplink transmission punching according to the association relation between the first target resource and the target sub-band. This implementation applies to the sub-band full duplex scenario shown in fig. 3.

In this implementation manner, the first target resource has an association relationship with the target subband, and the first terminal may determine, according to the association relationship between the first target resource and the target subband, the target subband that needs to be punctured, and how to perform uplink transmission puncturing on the target subband.

Wherein the target subband may be an uplink subband and/or a guard band. When the first radio access network device performs CLI measurement through an uplink sub-band, the target sub-band is an uplink sub-band, and the uplink sub-band is used for performing uplink transmission of the first terminal device to the first radio access network device; when the first radio access network device performs CLI measurement through the guard band, the target sub-band is an uplink sub-band, and the guard bands adjacent to the uplink sub-band. In this case, by determining the guard band, an uplink sub-band adjacent to the guard band is determined from the guard band, thereby determining a target sub-band.

In one possible implementation manner, the first indication information includes: and second time domain resource sub-indication information, wherein the second time domain resource sub-indication information is used for indicating the time domain offset and/or the time domain length of at least one resource element contained in the first target resource on the target sub-band.

In this implementation manner, the time domain offset indicated by the second time domain resource sub-indication information is based on the offset of the time domain starting position of the target sub-band, and the time domain length refers to the length of the continuous time domain symbol that needs to be punctured during puncturing. The first wireless access network device can indicate the position of each RE belonging to the first target resource on the target sub-band through the second time domain resource sub-indication information, so that the effect that the first terminal device does not perform uplink transmission on the first target resource is achieved through punching on the target sub-band, and the influence of the uplink transmission of the first terminal device on the first target resource on CLI measurement is eliminated.

Optionally, when the resource elements included in the first target resource are all continuous on the target sub-band, the starting position of puncturing may be determined according to the time domain offset, and the number or length of the time domain symbols to be punctured may be determined according to the time domain length.

Optionally, when the resource elements included in the first target resource are only partially continuous or are not continuous in the target sub-band, the time domain position of each part of the resource elements may be determined according to the information of the multiple pairs of time domain offsets and the time domain lengths included in the second time domain resource sub-indication information.

Optionally, when the location of the resource element included in the first target resource on the target subband starts from the starting time domain location of the target subband and all the resource elements are continuous, the time domain location where the puncturing is needed on the target subband may be determined only by the time domain length.

Alternatively, when the intervals of the resource elements included in the first target resource on the target sub-band are all fixed, the time domain position where the punching is required on the target sub-band can be determined only by the time domain offset.

It should be understood that the foregoing are merely a few possible implementations of determining the time domain position of the target subband puncturing according to the time domain offset and/or the time domain length of at least one resource element included in the first target resource provided in the embodiment of the present application, and the determination manners adopted by the present application in different situations are not limited and are not listed herein.

In another possible implementation manner, the first indication information includes: a first bitmap corresponding to the target sub-band; and the at least partial bit in the first bitmap is associated with a resource element included in the first target resource and is used for indicating the resource element included in the first target resource to perform uplink transmission punching.

In this implementation, the first bitmap is used to indicate some or all of the resource elements on the target subband, and the bit included in the first bitmap indicates the time domain position of the resource element included in the first target resource on the target subband, so as to determine the puncturing position on the target subband. Fig. 6 is a schematic diagram of a first bitmap according to an embodiment of the present application. In the first bitmap, 0 indicates a time domain position where puncturing is required, and 1 indicates a time domain position where puncturing is not required. And the first terminal equipment performs uplink transmission punching on the time domain position corresponding to the position with the bit position of 0 according to the first bitmap corresponding to the target sub-band. One bit in the first bitmap may represent one RE or multiple REs, which is not limited in the present application.

Implementation A2-3: and indicating uplink transmission punching according to the association relation between the first target resource and the frequency domain resource. This implementation applies to the sub-band full duplex scenario shown in fig. 3.

In this implementation manner, the first target resource has an association relationship with the frequency domain resource, and the frequency domain resource is determined according to the frequency domain corresponding to the CLI measurement resource. The first terminal may determine how to perform uplink transmission puncturing according to the association relationship between the first target resource and the target subband. The frequency domain resource is a frequency domain resource of an uplink transmission resource of uplink transmission from the first terminal equipment to the first radio access network equipment.

A possible implementation manner, the first indication information includes: and third time domain resource sub-indication information, wherein the third time domain resource sub-indication information is used for indicating the time domain offset and/or the time domain length of at least one resource element contained in the first target resource.

In this implementation, the method of determining, by using the third time domain resource sub-indication information, the position of at least one resource element included in the first target resource on the frequency domain resource is different from the method in implementation A2-2 only in that the starting position of the time domain offset reference is different. In this embodiment, the starting position of the time domain offset reference is the 0 position of the frequency domain resource, and is not the starting position of the uplink subband in the uplink resource. For other similar matters, the present application is not described herein.

In another possible implementation manner, the first indication information includes: and a second bitmap corresponding to the target frequency domain resource. And the second bitmap is used for indicating the resource elements included in the first target resource to perform uplink transmission punching. One bit in the second bitmap may represent one RE or multiple REs, which is not limited in the present application.

In this implementation manner, the punching position of the resource element included in the first target resource on the target frequency domain resource is indicated by the second bit, which is similar to the corresponding method in the implementation manner A2-2, and will not be described herein again.

Note that, in the foregoing implementation A2, the first indication information of the uplink transmission puncturing based on the RE level may be carried in DCI and sent to the first terminal device. The DCI may be DCI of an existing format, for example, DCI 2_4. For example, the first indication information may be carried by using an original IE in the DCI 2_4, or an IE for carrying the first indication information may be newly added in the DCI 2_4. The DCI may be a newly added format DCI, which is dedicated to carrying the first indication information, etc.

According to the method of the implementation mode A2 provided by the embodiment of the application, the part, overlapping with the CLI measurement resource, of the uplink transmission resource of the first terminal equipment is perforated for the RE level through various implementation modes, so that the first terminal equipment does not carry out uplink transmission to the first radio access network equipment at the punching position of the uplink transmission resource, thereby eliminating the influence of the uplink transmission of the first terminal equipment on the CLI measurement of the first radio access network equipment, and improving the accuracy of the CLI measurement between the first radio access network equipment and the second radio access network equipment.

It should be understood that the foregoing description is merely exemplary of how the uplink transmission puncturing is performed, where the resource is divided in units of RBs, or in units of REs. In particular, other division units may be used for uplink transmission puncturing, which is specifically related to the resource division unit used in the communication system, and will not be described herein.

S502, the first terminal equipment determines that the first target resource is not used for uplink transmission to the first radio access network equipment according to the first indication information.

That is, the first terminal device does not perform any uplink transmission on the first target resource. In this way, the uplink transmission puncturing of the first terminal device on the first target resource can be achieved.

The method provided by the application can avoid the first terminal equipment from carrying out uplink transmission to the first radio access network equipment at the punching position by punching on the uplink transmission resource of the first terminal equipment for carrying out uplink transmission to the first radio access network equipment, thereby eliminating the influence of the uplink transmission of the first terminal equipment on the CLI measurement of the first radio access network equipment.

Implementation mode B: changing the beam direction of the uplink transmission resource of the uplink transmission terminal equipment.

Fig. 7 is a flow chart of another communication method according to an embodiment of the present application. As shown in fig. 7, the method may include:

S701, the first radio access network equipment sends second indication information to second terminal equipment in the cell coverage area of the first radio access network equipment according to the CLI measurement resource configuration.

Correspondingly, the second terminal device receives second indication information from the first radio access network device.

The second terminal device is the same as the first terminal device in implementation a, and is used for uplink transmission to the first radio access network device in the coverage area of the cell of the first radio access network device, and the main difference between the second terminal device and the first terminal device is that the uplink transmission resource is adjusted in a different manner. The second indication information is used for indicating the second terminal equipment to perform CLI measurement between the terminal equipment on the second target resource. The second target resource includes: and the uplink transmission resource of the second terminal equipment overlaps with the CLI measurement resource indicated by the CLI measurement resource configuration.

With continued reference to fig. 2, when there is a third terminal device for downlink transmission in the coverage area of the cell of the first radio access network device, since the third terminal device and the terminal device for uplink transmission have opposite transmission directions at the same time point, a CLI between the third terminal device and the terminal device for uplink transmission exists between the terminal devices, and the reason for generating the CLI between the terminal devices is similar to that between the radio access network devices in the Dynamic/Flexible TDD scenario, which is not described herein again. Therefore, to solve CLI between terminal equipments, CLI between multiple terminal equipments is also required to perform measurement.

Therefore, in this embodiment, the second terminal device may perform CLI measurement between the terminal devices with the downlink terminal in the cell coverage area of the first radio access network device according to the indication of the second indication information. In the embodiment of the application, the third terminal device is a downlink terminal in the cell coverage of the first radio access network device.

The first radio access network device determines CLI measurement resources according to the CLI measurement resource configuration. And then, according to the CLI measurement resource, the second terminal equipment utilizes the uplink transmission resource to carry out CLI measurement between the terminal equipment and other terminal equipment so as to reduce the influence of the uplink transmission of the second terminal equipment on the CLI measurement.

S702, the first radio access network device sends third indication information to third terminal devices in the cell coverage of the first radio access network device. The third indication information is used for indicating the third terminal equipment to perform CLI measurement on the second target resource. And the third terminal equipment has the downlink terminal equipment in the cell range covered by the first radio access network equipment, and the downlink transmission resource of the third terminal equipment overlaps with the second target resource. And the third terminal equipment performs CLI measurement among the terminal equipment on the second target resource according to the received third indication information.

It should be understood that the present application is not limited to the order between the action of the first radio access network device sending the third indication information to the third terminal device and the action of the first radio access network device sending the second indication information to the second terminal device. The first radio access network device may send the second indication information first, or may send the third indication information first. In fig. 7, the present application takes the example of executing step S701.

Or the first terminal device may broadcast its resource configuration for CLI measurement, so that after a third terminal device in the coverage area of the cell of the first radio access network device monitors the broadcast, CLI measurement between terminal devices is performed on the second target resource.

S703, the second terminal equipment performs CLI measurement between the terminal equipment on the second target resource according to the second indication information.

A possible implementation manner, the second indication information includes: identification of the reception beam employed when the first radio access network device CLI measures.

The identifier is used to indicate the reception beam used by the first radio access network device CLI in measurement, and the identifier may be, for example, an index of the reception beam, a character capable of referring to the reception beam, or the like, which is not limited by the present application. The second terminal device determines a first transmitting beam with minimum reference signal receiving Power (REFERENCE SIGNAL RECEIVING Power, RSRP) between the first transmitting beam and the receiving beam according to the identification of the receiving beam adopted when the CLI of the first radio access network device is measured. And transmitting an interference signal on the second target resource by using the transmission beam, so that other terminal equipment performs CLI measurement between terminals based on the interference signal.

Since the RSRP of the first transmission beam and the reception beam on the uplink transmission resource where the reception beam used for CLI measurement between the radio access network devices is located is the smallest, the influence of the second terminal device on CLI measurement of the first radio access network device can be reduced.

In another possible implementation manner, the second indication information includes: and the second terminal equipment performs identification of a first transmission beam adopted by the inter-terminal equipment CLI measurement on the target resource. That is, in this implementation, the transmit beam employed by the second terminal device is determined by the first radio access network device. The manner in which the first radio access network device determines the transmission beam adopted by the second terminal device may, for example, be the manner in which the second terminal device determines the transmission beam as described above, which will not be described in detail.

In another possible implementation manner, the second indication information includes: the identification of the receiving beam adopted by the first radio access network equipment CLI measurement and the identification of the first sending beam adopted by the second terminal equipment for the inter-terminal equipment CLI measurement are carried out on the target resource. That is, in this implementation manner, the first radio access network device primarily determines the transmission beam adopted by the second terminal device, and after receiving the second indication information, the second terminal device may comprehensively determine the final transmission beam according to the identification of the reception beam adopted by the first radio access network device during CLI measurement, and primarily determine the transmission beam adopted by the second terminal device.

The second indication information and the third indication information in the above-mentioned implementation B may be DCI in a newly added format, and are specifically configured to carry the second indication information or the third indication information.

According to the method provided by the embodiment of the application, the direction of the sending beam of the second terminal equipment is changed, so that the CLI measurement between the terminal equipment is executed on the second target resource while the second terminal equipment does not carry out uplink transmission to the first radio access network equipment, and the utilization rate of uplink transmission resources is also improved under the condition that the influence of the uplink transmission of the second terminal equipment on the CLI measurement of the first radio access network equipment is reduced.

Implementation C: and adjusting the uplink transmission resource of the uplink transmission terminal equipment to be a resource orthogonal to the CLI measurement resource.

In this implementation, the CLI-measurement resource configuration includes Demodulation reference signals (Demodulation REFERENCE SIGNAL, DMRS) used for CLI measurement, and CLI-measurement resources.

S801, the first radio access network device sends fourth indication information to fourth terminal devices in the cell coverage of the first radio access network device according to the first DMRS.

Correspondingly, the fourth terminal device receives fourth indication information sent by the first radio access network device.

The fourth terminal device is also a terminal device for performing uplink transmission to the first radio access network device within the coverage area of the cell of the first radio access network device, which is not described herein again. The fourth indication information is used for indicating a second DMRS used by the fourth terminal device for uplink transmission on the third target resource, where the second DMRS is orthogonal to the first DMRS. The third target resource includes: and the uplink transmission resource of the fourth terminal equipment and the CLI measurement resource overlap.

And when the first wireless access network equipment and the second wireless access network equipment interact with the CLI measurement resource configuration, acquiring a time-frequency position corresponding to the CLI measurement resource and a DMRS sequence. The time-frequency position is a time-frequency position indicated in a first DMRS (uplink DMRS) of the first radio access network device, where the uplink DMRS is a DMRS corresponding to an uplink transmission resource of the first radio access network device, and the resource sequence is the same as a sequence of the first DMRS (uplink DMRS) of the first radio access network device. And the first wireless access network equipment determines the time-frequency position of a second DMRS and the DMRS sequence used for indicating the fourth terminal equipment to carry out uplink transmission on the third target resource according to the time-frequency position and the DMRS sequence. The time-frequency position indicated by the second DMRS is the same as the time-frequency position indicated by the first DMRS, the sequences are different, and the second DMRS is orthogonal to the first DMRS.

And the first wireless access network equipment determines fourth indication information according to the time-frequency position indicated by the first DMRS and the DMRS sequence. The fourth indication information may be a time-frequency location including the first DMRS indication, and the DMRS sequence; or may include a time-frequency location of a second DMRS obtained from the first DMRS, and a DMRS sequence; or the second DMRS is pre-stored in the fourth terminal device, and the fourth indication information is merely indicative of how the fourth terminal device selects the second DMRS, for example, the fourth indication information may include an identifier of the second DMRS, and so on.

S802, the first radio access network device measures CLI between the first radio access network device and the second radio access network device on the CLI measurement resource, and receives an uplink transmission signal of the fourth terminal device on the third target resource.

And the fourth terminal equipment determines a second DMRS according to the implementation mode of the fourth indication information, and determines a third target resource according to the second DMRS, and the fourth terminal equipment performs uplink transmission to the first radio access network equipment on the third target resource, wherein the third target resource is orthogonal with the CLI measurement resource used for CLI measurement by the first radio access network equipment. According to the orthogonality of the DMRS, at this time, the fourth terminal device performs uplink transmission to the first radio access network device on the third target resource, which can reduce the influence on CLI measurement of the first radio access network device.

Note that, the fourth indication information in the above implementation C may be carried in DCI and sent to the fourth terminal device. The DCI may be DCI in an existing format, for example, the fourth indication information may be carried by using an original IE in the existing DCI, or an IE for carrying the fourth indication information may be newly added to the existing DCI. The DCI may be a newly added format DCI dedicated to carrying the fourth indication information, etc.

According to the method provided by the embodiment of the application, the uplink transmission resource of the fourth terminal equipment is adjusted to be the resource orthogonal to the CLI measurement resource, so that the influence of the uplink transmission of the fourth terminal equipment to the first radio access network equipment on the third target resource on the CLI measurement of the first radio access network equipment is reduced according to the orthogonality of the DMRS, the technical effect that the second terminal equipment can still perform uplink transmission to the first radio access network equipment when the CLI measurement of the first radio access network equipment is realized, and the resource multiplexing rate is improved.

For the three uplink transmission resource indication methods provided in the foregoing embodiments, when there are multiple uplink transmission terminal devices in the cell coverage of the first radio access network device, the same uplink transmission resource indication method may be performed on all uplink transmission terminal devices, or different uplink transmission resource indication methods may be performed on different uplink transmission terminal devices at the same time.
